CRS-11 Dragon Resupply Mission Mission Overview SpaceX’s Falcon 9 rocket will launch a Dragon spacecraft to low-Earth orbit to deliver critical cargo to and from the International Space Station for NASA. SpaceX is targeting launch of its eleventh Commercial Resupply Services mission CRS-11 from Launch Complex 39A at NASA’s Kennedy Space Center, Florida. The instantaneous launch window is on Thursday, June 1 at 5:55 p.m. EDT with a backup launch attempt on Saturday, June 3 at 5:07 p.m. EDT, Dragon will separate from Falcon 9’s second stage about 10 minutes after liftoff and attach to the space station on June 4. The CRS-11 mission will be the 100th launch from historic LC-39A at Kennedy Space Center. Following stage separation, the first stage of Falcon 9 will attempt to land at SpaceX’s Landing Zone 1 (LZ-1) at Cape Canaveral Air Force Station, Florida. Dragon Spacecraft Dragon will be filled with almost 6,000 pounds of supplies and payloads, including critical materials to directly support dozens of the more than 250 science and research investigations that will occur during Expeditions 52 and 53. The Dragon spacecraft being used to support the CRS-11 mission previously resupplied the International Space Station on SpaceX’s CRS-4 mission in September 2014. SpaceX CRS-11 is the eleventh of up to 20 missions to the International Space Station that SpaceX will fly for NASA under the first CRS contract. In January 2016, NASA announced that SpaceX’s Falcon 9 launch vehicle and Dragon spacecraft were selected to resupply the space station through 2024 as part of a second Commercial Resupply Services contract award. Under the CRS contracts, SpaceX has restored an American capability to deliver and return significant amounts of cargo, including live plants and animals, to and from the orbiting laboratory. A variant of the Dragon spacecraft, called Dragon 2, is being developed for U.S.- based crew transport to and from the station.
